From 46f1130b5286457e519c296a4b683747deb983cb Mon Sep 17 00:00:00 2001 From: Philipp Rossak Date: Wed, 24 Jan 2018 16:58:30 +0100 Subject: [PATCH 027/146] iio: adc: sun4i-gpadc-iio: add support for H5 thermal sensor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds support for the H5 ths sensor. The H5 supports interrupts. The interrupt is configured to update the sensor values every second. The sensor is except the scale/offset values and an additional sensor for the gpu the same. A temperatur higer than 70°C needs an other formula. Since the operating temperatures maximum is 70°C this case was neglegted.
